Costume jewelry necklace featuring yellow cabochons in the manner of mid-20th-century floral-themed designers

This appears to be a vintage-style costume jewelry necklace composed of five visible gold-toned metal links. Each link features a large, oval, yellow-colored cabochon that exhibits a speckled or confetti-like internal texture, possibly made of resin or poured glass with inclusions. These settings are nested within stylized gold-toned botanical motifs, including textured leaf-like elements that curve around the bases of the stones. A small black rectangular tag is suspended from one of the links, bearing a gold-toned graphic that resembles a stylized 'S' or swan, consistent with marks used by mid-century costume jewelry manufacturers like Sarah Coventry. However, without physical examination, this identification remains a hypothesis as tags can be added or replicated. The necklace demonstrates construction methods typical of the 1950s or 1960s, such as articulated link joints and textured metal plating. The condition appears fair to good with some visible darkening or tarnish on the metal links and what seems to be a slight residue or aged adhesive near one of the central cabochon settings. The item exhibits attributes of collectible costume jewelry from the mid-20th century, though provenance cannot be definitively established from an image alone.

Based on the image provided, I have evaluated this vintage-style costume jewelry necklace featuring gold-toned botanical links and yellow cabochons. Based on what I can see, the piece bears a signature/mark consistent with manufacturers such as Sarah Coventry, specifically under the working hypothesis that the 'S' graphic on the tag is an period-appropriate mark. The internal confetti-like texture of the stones suggests a resin or poured glass construction typical of mid-20th-century floral-themed costume jewelry. The estimation is based on the assumption that this attribution is correct. If the piece were later found to be an unattributed 'in the style of' reproduction or a modern replica, the value would likely decrease to the $15–$25 range. Conversely, if physical inspection reveals higher-quality materials like Lucite or poured glass by a more prestigious maker like Trifari, the value could exceed the current estimate. I cannot verify from a photo the exact composition of the metal or the setting security; I note some visible tarnish and potential adhesive residue that may impact the final sale price. The market for mid-century costume jewelry remains stable among collectors who value the aesthetic of the 1950s and 60s. To confirm the identity and value, a physical examination would be necessary to verify the weight, the construction of the articulated links, and the specific application of the hallmark. Until provenance documentation or a hands-on hallmark verification is conducted by a specialist, this remains an estimated range for a piece of this type.
